An Opacity Control Slider for Google Maps

Gavin Harris has released the code for an Opacity Control for Google Maps. The control is a slider button that can be used to adjust the opacity of map overlays used with the Google Maps API v3.

The slider control can be seen in action on NZ Topo Map, where it is used to control the transparency of topographic map tiles. The code is available for download and use by Google Maps API v3 developers under a Creative Commons Licence.
